Did Robin Thicke's unrated music video for "Blurred Lines" cross the line?

That seems to be the case (at least in the eyes of some) since the clip, which features a bevy of topless beauties, can no longer be found on YouTube. A much tamer version, however, remains on the site.

"YouTube took down the Unrated version of #BLURREDLINES because it was too hot," Thicke tweeted on March 30.
